(min age: 5th grade) Students will start with a huge mound of cardboard, scissors and a roll of duct tape. Then they will be given an object to build out of the materials that must properly perform its given function. Maybe they need to build a boat out of cardboard that will transport one of their classmates across our lake! Or maybe they need to build a nice chair that can hold their chaperone! Whatever the object, students have to plan, build, and test their way to a final product.
